I’d rather go quietly into the night when the time comes that I’m not self sufficient (via assisted suicide). Perhaps that’s wishful thinking, and I won’t have the mental fortitude at that time.
Also likely, "culture of life" virtue signallers will prevent you from doing what's right for you by nudges that make suicide difficult, painful, and illegal. Part of your plan should be to support assisted suicide politically. For example, Neil Gorsuch wrote a book advocating against euthanasia, making him one of the worst Supreme Court picks I can imagine. https://press.princeton.edu/titles/8317.html
